I have been using this HDD (see my post #2079
The USB external hard disk that I am using has its own power supply, and it works fine with all other recording channels. But I will see if I can find a different hard disk; perhaps a Samsung 850 Solid State disk.
I don't use the Guide; I use TitanTV and set the recordings manually using time/date. But I'll check the Guide for Ch6 (RF9) tonight and see how far out it extends.
Regarding the RF interference issue, since Ch6 (RF9) is the lowest channel that I receive then that might be an issue. It doesn't explain why I can see the station clearly; I only have problems recording it. Unless the RF EMI is messing with the digital-to-digital stream chips somehow (the chips that take the digital stream and put onto the USB cable).
The problem channel is Ch6, RF9, KVIE, PBS. Note that the next highest RF next channel that I get (Ch10, RF10, KXTV, ABC) doesn't have these problems:
- Ch6 RF9 is at 186-192 MHz and TVfool says I should see a signal level of -65dBm.
- Ch10 RF10 is at 192-198 MHz and TVfool says I should see a signal level of -63.6dBm.
The VRX2 signal strength meter does indeed show a difference of 1 bar between these to channels. And these are adjacent elements on my antenna. See attached tvfool PNG output table for reference. In the table, the ones that I've marked off in red
are in Fresno (south) and my antenna is pointing towards Sacramento (the Walnut Grove antenna farm 60 miles north of me).
Regarding the anti-recording flag in the digital stream, I would assume that if this were the problem then the VRX2 wouldn't record the show at all. As it is, it just skips a few seconds of audio/video every now and then (it appears as random skips, not regular; sometimes numerous skips in a row, other times it is clean for a couple minutes).
Regarding the signal itself, does the VRX2 have a way to show the data rate in real time? I haven't seen anything like this in the menu system.
Thanks to all, I will check-out these issues tonight.
